Al/Ni energetic laminates with various Al/Ni thickness ratios were prepared by electrodeposition and hot pressing method toinvestigate the effect of the thickness ratios on mechanical properties and exothermic energy of the composites. In this study,the different Al/Ni thickness ratios of 9:4, 9:6, 9:8 and 9:10 were determined by varying the initial thickness of Ni layers. Theresults showed that the Al/Ni laminate with the thickness ratio of 9:4 had the largest exothermic heat of 1139 J/g, while thelaminate with 9:10 possessed the optimum mechanical properties, such as the tensile strength of 395.8 MPa, the elongationof 13.3% and the bending strength of 706 MPa. It was found that the tensile properties and plastic forming properties of thelaminates were enhanced continuously with the increasing proportion of nickel layers due to higher strength and the improvingcollaborative deformation of Al/Ni multilayers, when the Al/Ni thickness ratio altered from 9:4 to 9:10. Meanwhile,the exothermic reaction energy was declined significantly because of the increasing proportion of the exothermic reactionto form AlNi3compounds, which possessed the lower energy density. In addition, the effect of Al/Ni thickness ratio on thereaction paths in the continuous heating process was also studied.
